  • Patent number: 11039712
    Abstract: A beverage machine, in particular a coffee machine, prepares a beverage using water supplied via a fixed water connection to a hydraulic part arranged in the beverage machine and outputs the beverage at an outlet of the beverage machine. Maintenance is simplified by the fact that the beverage machine is provided with a cartridge holder which is accessible from the outside and into which a cartridge can be inserted in an exchangeable manner, the cartridge includes a cartridge connection on the inlet side and a cartridge connection on the outlet side, via which, in the inserted state of the cartridge, water supplied to the beverage machine via the fixed water connection flows through the cartridge and is thereby filtered and/or enriched with additives.

  • Patent number: 8528464
    Abstract: A brewing facility for a coffee machine comprises a brewing cylinder (6) and an upper plunger (3) and a lower plunger (4) by means of which a brewing chamber is formed. The brewing cylinder (6) and the plungers (3 and 4) are held in a frame (2) such that they can be shifted, and can be driven by means of a driving facility. For adding the coffee powder, a coffee powder feed facility is provided which in turn is provided with a swivel-type funnel (14), which can be moved against a spring force from a filling position into a swiveled-away position, and vice versa. The swivel-type funnel (14) can be swiveled further from the swiveled-away position to a fully swiveled-out position and, in said fully swiveled-out position, can be locked by locking means (29) and unlocked by unlocking means (30). In this way, the swivel-type funnel (14) can be held in the fully swiveled-out position during the cleaning of, in particular, the upper plunger (3).

  • Patent number: 8444016
    Abstract: An apparatus for dispensing milk-based beverages comprises a milk container (4), a pump (8) for conveying the milk from the milk container (4) to a milk outlet (20), supply means (13, 14) for supplying at least one flavoring agent to the milk and means for mixing the at least one flavoring agent with the milk. To this end, a coolable cabinet (2), into which the milk container (4) can be inserted, is arranged in a housing (1). Via a hose line (7), the milk in the milk container (4) reaches a mixing apparatus (9) in a meterable quantity, conveyed by the pump (8) disposed in the hose line (7). At least one flavoring agent is able to be additionally supplied in a metered manner into the mixing apparatus via the supply means (13, 14), and is able to be mixed with the milk; the mixed beverage thus obtained reaches, via an outlet (20), a vessel (21) which can be provided beneath this outlet (20). Flavored cold milk-based beverages can thereby be produced in an optimal way.

  • Patent number: 7475628
    Abstract: In a device for dispensing milk and/or milk froth from a container (1) containing milk, this container is placed in a coolable cabinet (3). Via an extraction line (4) and a further line (5), the milk reaches an emulsifying device (6) disposed outside the coolable cabinet. The product received is dispensed from this emulsifying device (6) via the discharge nozzle (7). Steam is feedable into the emulsifying device (6) with which steam the milk conducted through the emulsifying device (6) is able to be heated up and/or frothed up. The further line (5) consists of a flexible tube which is placed in a peristaltic pump (9). This peristaltic pump (9) is equipped with switching means (10) with which the peristaltic pump (9) is switchable from a closed pump state into an open pump state releasing the passage of the flexible tube (5). Milk of different temperatures or milk froth can be optimally dispensed using this device; in addition an optimal cleaning can be carried out.
